The Clayton Steam generator has been continually developed since 1930 and is very different from the traditional firetube boiler design that is the familiar steam train boiler image of the past. In a firetube boiler a large amount of water and steel is heated to produce steam. In the Clayton Steam generator a small amount of water and steel is heated to produce steam. The basic design concept results in a steam making machine with staggering advantages for today’s world.
There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and " steam boiler " or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.

Mar 21, 2014 · The heat enters the water, converting it to steam and creating thermodynamic energy. This thermodynamic steam energy then acts as the energy source needed to power the massive turbines that create the power. Types of Boilers. Boilers are often categorized as either fire-tube boilers or water-tube boilers.
Boiler is a device used to generate steam at a desired pressure and temperature by transferring heat energy produced by burning fuel to water to change it to steam. Normally boiler is a combination of apparatus used for producing, furnishing or recovering heat together with the apparatus for transferring the heat so made available to the fluid being heated and vaporized.
